CHARLES SCHEUNER, OF CHICAGO, ILLINOIS.

Application sied January 17, 1922. serial No. 529,887. l c Y* To all whom it may concern: f

Be it known that I, CHARLES SCHEUNER, a citizen of the United States, resident of Chicago, in the county of Cook and State of Illinois, have made a certain newand useful Invention in Armored Pneumatic Tires; and vl declare the lfollowing to be 'a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a transverse'section of the in- -vention on the line 1 1, Figure 7.

Figure 2 is a detail fragmentary side view of one of the longitudinal halves of the casing.

Figure 3 is a detail perspective view 0f one of the' springs.

Figures 4 and 5 are detail cross sectional showing the meansv for connecting the two halves thereof and taken respectively on the lines 4-4 and 5--5, Figure 7 Fi ire 6 is a side view of the tire showing lamps in position to draw the two sections of the tread together.

Figure 7 is a detail longitudinal sectional view showing the application of one of these clamps. Y

The invention has relation to armored or puncture proof pneumatic tires, having for an object tol provide such a tire that may be -mou-I1ted'upon thev -wheels of automobiles in the customary manner,and wherein-thelreff siliencyf `of the tire will ,be preserved, vthe in- *ner tubepartially relieved of strain, and *effective `ar-Inorcombined therewith.` Other 'ects and advantages willappear from the A'The invention consists inthe novel. construction and combinations ofrparts, as here- -inafter set forthqvf Y. .i 1 'Inthe accompanyingfdrawings illustrat ing the invention, the numeral 1, designates the-'rim oflthe tire,imade up in two annular sections, usu'allyof wood, and bounded by Yannular metal plates,-2, 3,14, and 5', the lateralfplates 11` and 51am] .the said sections being transversely perforated at, forreasons `that-'willberstated. .i 1 i .y ij f `7 fdesign'ates'thejmembers vofan annular seriesaof metallic-Ispringssmadeof very thin xsteel, and# consistingeach 'of an inner. .ver- 'ftieal straight-riportionvfS, a .concavdconvex :or

The inner tube 13-of the tire is'loca'tedf within and inclosed by the two seriesiof springs and the said rim, and located between the horizontal outer portionsA oflt'he said springs and the tread portion 'ofthe inner tube is anr annular-strip 14 ofleathereor fabric,serving tol protect the 'inner-:tube from abrasion bytheV overlying springsat Ithe tread portion of the said tube. :.i.

For the same reason, i. e. to connect the two halves of thetire and to `prevent the said halves from moving either annularly or laterally relative t'o each other, the said elastic band is provdedat intervals with transverse metal strips orties V26 having end yperforations 27 engaging vertical studs '28 .ofthe tread portion of each half of the tire,

said transverse strips 26 fitting closely within transverse recesses 27, the latterdividing the inner strips 2l into arcuate portions, and

As means' of preventing any circumferential or annularmovement ofthe tread 29 upon the tire proper, the arcuate sections are hinged together at 3'6", and are drawn f together by clamps 37 'or the like, before the insertion ofthe hinge pins 38, the latter holding the arcuate tread sections in complete annular form.
